The BCMSN book by Cisco Press has a table that says EIGRP supports a maximum of 50 routing peers and that the maximum number of switch blocks is dictated by this limitation. I found no documentation on Cisco's website to support that claim. Does anyone know what they're talking about? Is a peer considered a neighbor? If so each router in my company has hundreds of neighbors and we have no eigrp problems.

Max EIGRP Routing Peers?

Hundreds in the same AS? I doubt it. One route change or stuck in active would bring your entire network to it's knees. The number 50 is a safe limit based on alot of things.
Not to mention that many times if you are using EIGRP, you are running something else other then plain IP across the network. On the last large network I worked on ( +500 routers) we had IP and IPX. THe router has to maintain a route table for BOTH protocols so it really chews up the memory with lots of routes unless you have some decent route filtering in place(which we did not)
If you want the last word on Cisco EIGRP then get a copy of "EIGRP Network Design Solutions" by Cisco Press.
